I'm having probs with my new VCR, not an old one! For some reason I can't tape digital channels, only analogue.

Anyway, back to subject: your VCR needs to be tuned to the channels available in your area. Plug it in, connect the aerial cable & scart, and look for a Menu or Setup button on your remote or on the machine. Press that, find an option which says auto-tune or channel setup, and see what happens.

Mine will only record from the AV channel if it 'forgets' the other channels, i.e. when it's unplugged for a length of time.
